Undead Revival

You plant a mortal soul within an undead vessel, defying their natural death. This spell requires a mortal soul to be imbued into the target.

Within range, the souls of humanoids that have died within the last hour are made visible to you, appearing attached to their mortal bodies by fraying, green strands of spectral energy. One of these souls may be captured and used for the casting of this spell. Unless such a soul is being used to cast this spell, you cannot capture it with this spell.

As well as souls captured by this spell, you may employ souls captured with other spells such as Soul Cage, Magic Jar, or a soul that you have bargained for and keep on your person, such as a soul trapped in an infernal reliquary.

Target a corpse within range and present a humanoid soul in your possession. You animate that corpse using the soul, transforming them into an undead creature resembling a zombie or a skeleton. They gain the statistics, including hit points and ability scores, that they had in life, as well as any saving throw proficiencies, skill proficiencies, feats, class abilities or other learned abilities. Even if they occupy their own former body, they had any racial traits, they are replaced with the following:

• Undead: Your creature type is undead.
• Darkvision: You have darkvision with a range of 60 feet.
• Unnatural Composition: You are immune to poison damage and the poisoned condition. You are also immune to disease.
• Undead Fortitude: If damage would reduce you to 0 hit points, make a constitution saving throw with a DC of 5 + the damage taken, unless the damage is radiant or from a critical hit. On a success, you drop to 1 hit point instead.
• Undead nature: You do not need to eat, drink, or breathe. When you make death saving throws, you fail on rolls of 10 or higher and succeed on rolls of 9 or lower. If you would stabilize from succeeding on three death saves, you return to 1 hit point instead.

An unwilling creature can make a Wisdom saving throw to avoid returning as an undead. On a success, the spell dissipates and the target is immune to the effects of this spell for 24 hours.

Unless the soul was obtained through a contractual bargain, the undead individual possesses full autonomy and is under no obligation to serve you or interact with you. If you did own their soul, they are compelled to obey all of your spoken commands, but may otherwise act freely.

The soul may occupy an body created by this spell for a total number of years equal to half of the natural lifespan of their original race, after which point their body crumbles to dust and their soul moves on immediately. If the undead individual dies before this point, their soul lingers, attached to the now lifeless vessel, for one hour, allowing them to be revived by this spell again.
